本實驗選用碳化鎢與SKD61熱作模具鋼兩種異質材料,其中碳化鎢分有Ni基碳化鎢與Co基碳化鎢,利用Cu-9Sn青銅片做為硬焊填料,於滲碳性氣氛下進行接合。透過不同持溫時間作為硬焊參數,觀察接合件之微觀結構、硬度及剪切測試,探討不同Ni含量與Co含量之碳化鎢/焊料/SKD61間界面反應,以及不同持溫時間對WC-13%Co (KE13)碳化鎢接合件對環境耐衝蝕性的變化。線掃描(Line scan)結果顯示,Co基碳化鎢兩側界面處皆有富含Fe及Co的相出現,Ni基碳化鎢接合件可觀察到大量Cu擴散進碳化鎢。剪切實驗結果顯示硬焊條件為1050℃持溫20分鐘時, WC-14%Ni (NA30)有最大的剪切強度313MPa。沖蝕試驗結果顯示,經過滲碳性氣氛處理之WC-13%Co (KE13)及SKD61鋼材於硬焊條件為1050℃持溫20分鐘時,擁有最好的耐沖蝕性。
The brazing of Tungsten Carbide, WC-Co and WC-Ni, and SKD61 under carburizing atmosphere by Cu-9Sn foil has been studied. The microstructure observation, hardness and the shear strength of the brazed joint, the effect of the brazing time, interface reaction of filler and different Ni or Co content in the cermets on the joint behavior have been discussed in the article. The shear strength test results showed the max shear strength of the joints, WC-14%Ni/Cu-9Sn/SKD61, 313 MPa was derived at 1050°C 20 min. The line scan test showed Fe/Co rich phase were observed in interface, much Cu diffused into WC-Ni. After four hours slurry erosion test, the mass loss of WC-13%Co (KE13)/SKD61 joints was the minimum.
